GXF-3 is the current exchange standard for gridded gravity and magnetics data. The SEG
Gravity and Magnetics Committee approved GXF-3 in 2000 for formalization by the SEG
Technical Standards Committee.

GDF-2 is the current exchange standard for point/line gravity and magnetic data. The SEG
Gravity and Magnetics Committee approved GDF-2 in 2000 for de facto use by the gravity and
magnetics community until such time when the standard can be approved for formalization by
the SEG Technical Standards Committee
